(Contributed by Amaury Forgeot d'Arc and Antoine Pitrou.)
* A new configure flag, ``--with-computed-gotos``, enables a faster opcode
dispatch mechanism on compilers which support it. Speedups of up to 20%
have been observed, depending on the system and compiler.
(Contributed by Antoine Pitrou, :issue:`4753`.)
* Add a heuristic so that tuples and dicts containing only untrackable objects
are not tracked by the garbage collector. This can reduce the size of
collections and therefore the garbage collection overhead on long-running
